FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 362,173, dated May 3,1887.

Application filed March 6, 1886. Serial No. 194,339. (No model.)

To all whom, it may concern.-

Be it known that I, AMos NUDD, a citizen of theUnited States, residingat Chicago, in the countyof Cook and State of Illinois, have inventedanew and useful Fire-Escape, of which the following is a specification.

My invention relates to that class of fireescapes by which a person isenabled to pass quickly and safely down a single rope. It also providesa means of lowering to the ground a person helpless or otherwise, and,if required, more than one person at the same time. I attain theseseveral objects by the mechanism illustrated in the accompanyingdrawings.

Figure 1 is a front view of the device. Fig. 2 is an elevated side Viewof the same. Fig. 3 is a front view showing the position of the ropewhen arranged for a person to descend alone, the same being shown on areduced scale in Fig. 5. Fig. 4 is a front view showing the position ofthe rope when arranged for lowering a person to the ground, the samebeing still further shown on a reduced scale in Fig. 6. Fig. 6 is simplyan enlarged view of Fig. 5, showing more clearly the position of thebelt and fire-escape with the rope attached.

Similar letters refer to similar parts throughout the several views.

To the front surface of the plate A is attached the friction-cylinder B,the friction lugs or hooks O and D, and the snub-pin E. All these partsare made of brass, malleable iron, or other suitable metal.

The rope F, as shown in Figs. 3 and 5, passes under or behind thefriction lug or hook G, then around the friction-cylinder B one or moretimes, according to the amount of friction or resistance required, thenunder or behind friction lug or hook D, and, if still further resistanceis required, around the snubpin E, as shown in Fig. 1.

If the person descending wishes to stop before reaching the ground, hehas only to take an additional turn of the rope around the snub-pin E,when he will be securely held.

In order to loweraperson from any exposed position, as shown in Fig. 6,the rope, after passing under or behind friction lug or hook G andaround cylinder 13, passes again under lug or hook 0, (said lug or hook0 being double,) as shown in Fig. 4., and further shown in Fig. 6. Inall these movements the end of that part of the rope F which firstpasses under or behind the lug or hook O is firmly secured within theroom or at the window whence escape is being made. The other part of therope F is thrown to the ground, as shown in Fig. 5, or held in hand, asshown in Fig. 6. When, as shown in Fig. 6, the person reaches theground, the belt is disengaged, when it can be drawn up to the window tobe again used.

A person standing on the ground may take the rope F in hand, and thusleave to the person descending the free and full use of his limbs andenable him to take a child in his arms, and a person may step upon hisshoulders and hold himself in position by the rope F, the additionalweight being limited only by the strength of the rope.

Any number of firc-escapes with belts attached may be used by as manypersons, each throwing off the rope on reaching theground, thus enablingthem to follow each other in quick succession on one and the same rope.

The space between the lugs or books 0 and D and the plate A is justsuffieient to allow the close passage of the rope under or behind them.

The rope can be instantly thrown off on reaching the ground; but whilethe weight of the person rests upon it the direction of the draft issuch that it is impossible to disengage it.

The manner in which the rope F is held by a person standing on theground is shown by the hand I in Fig. 5.

The belt G passes through a slot, H, in the plate A, as shown in Fig. 2,and is secured to the person by an ordinary buckle.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination, with a belt, of the plate A, the friction'eylinder B,the friction lugs or hooks O and D, the snub-pin E, and the rope F, allsubstantially as described.

AMOS NUDD.
